CHRISTOPHER J GRELLNER, OF ST. LOUIS, MISSOURI.

HAMMER.

SPECIFICATION forming part of Letters Patent No. 341,474, dated May 11,1886.

Application filed December 21, 1885. Serial No. 186,324.

'NER, of the city of St. Louis, inthe State of Missouri, have invented acertain new and useful Improvement in Hammers, 8:00., of which thefollowing is a full, clear, and exact description, reference being badto the accompanying drawings, forming part of this specification, and inwhich- Figure 1 is a side View, part in section, of a hammer embodyingmy invention. Fig. 2 is an end view of the wedge. Fig. 3 is aperspective view of the wedge, and Fig. 4 is a similar view in amodified form.

This invention relates to an improvement on the device shown anddescribed in Letters Patent No. 261,338, granted to myself July 18,1882.

With my improved form of device the wedge is made in one piece, and hasan opening to receive the retaining member or nail.

Referring to the drawings, A represents the hammer, and B the handle.

0 represents the wedge,which is made with aperforation, D. Atthisperforation the wedge is preferably enlarged by ribs F, as shown,which taper downward to the taper G of the wedge. The perforation isturned outward to one side of the wedge, and when the nail or securingmember is driven down its end comes against theincline formed by turningthe perforations outward to one side of the wedge. W ith this form ofwedge and manner of securing it in place there is no friction betweenthe retaining member and wedge as the former is driven in, and the wedgeis securely and effectually held from coming out. The wedge is also inone part, which makes it cheaper,

(No model.)

and there is no danger of losing one of the parts, as where the wedge ismade in two parts.

In the modification shown in Fig. 4 the openings for the retainingmember are made in the ends of the wedge instead of the center, as shownin the other figures. In this modification are also shown ears 0, whichare intended to engage the top of the hammer-head each side of the eyeand to aid in holding the head upon the handle.

I claim as my invention 1. The combination of the hammer, handle,perforated wedge made in one piece, and retaining nail or member adaptedto enter the perforation in the wedge and to be turned outward at itslower end through the perforations into the wood of the handle, as shownand described.

2. The combination of the hammer, handle, wedge having a perforation,ribs strengthening the perforated portions of said wedge, and the nailor retaining member adapted to enter the perforation in the wedge and'tobe turned outward at its lower end into the wood of the handle, asdescribed.

3. The combination of the hammer, handle, perforated wedge, taperingribs strengthening the perforated portions of said wedge, and retainingnail or member, the perforation turning outward through side of thewedge to form an incline, that acts to turn up the lower end of the nailor retaining member into the wood of the handle, as described.
